We make inferences about the physical properties of heterogeneous media from scattered (elastic) waves. Indoors, these waves are mostly ultrasonic, excited and detected with lasers. Outside, probing waves are in the seismic frequency band.

As our wavelengths span orders of magnitudes, so do our applications. Outside, targets include the Auckland Volcanic Field, geothermal exploration, and micro-seismicity for fluid reservoir characterization. In the laboratory, we do rock physics in collaboration with the PORO lab, ice physics, medical imaging.

- New article on Photoacoustic Vector-FlowWe are pleased to report that a new article led by Caitlin Smith is now live and open access in Photoacoustics. Caitlin rigorously developed and validated a technique for photoacoustic vector-flow to measure the pixel-wise magnitude and direction of flowing optical absorbers. This work focused on ex vivo whole blood and a comparison to pulse-echo…
- Caitlin graduates with HonoursCongratulations to Caitlin on graduating with Honours and completing her thesis on photoacoustic velocimetry. After many months of waiting for an in-person graduation, Caitlin finally got to walk the plank this week! She has been such an asset to our biomedical imaging projects and we are thrilled she will be continuing her work in the…
- Shallow Water Waves and TsunamiTsunamis can be generated by earthquakes near subduction zones. Here, the white gutter represents one tectonic plate with water -- an ocean -- on top. The wooden board is a plate subducting under the "gutter plate." Friction between the two plates, pulls the gutter down until the friction is overcome by the strength of the…
